Blood returns waste products from tissues to the ____ to be elimated
kidneys
Layers of the heart?
Endocardium, myocardium, epicardium
receiving chambers
atria
pumping chambers
ventricles
septum
separates heart into left and right
carries blood away from the heart
arteries
returns oxygen-poor blood to the heart
veins
deliver oxygen and nutrients to cells of tissues
capillaries
plasma after blood cells and clotting proteins have been removed
serum
erythrocytes
red blood cells
thrombocytes
platelets, clotting agent
leukocytes
white blood cells, fights infection
neutrophils
most common type of WBC
basophils
least common type of WBC
eosinophils
WBC which destroys parasitic organisms and plays a major role in allergic reactions
lymphocytes
WBC which identifies germs and produces antibodies against them
monocytes
WBC which provides immune defense against many infectious organisms
systemic circulation
flow of blood to all parts of the body except for the lungs
pulmonary circulation
flow of blood only between the heart and the lungs
sinoatrial node
known as the natural pacemaker, starts each wave of muscle contraction
atrioventricular node
receives impulses from the SA node and transmits them to the bundle of His
bundle of His
ensures the sequence of heart contractions, transmits impulses to the Purkinje fibers
Purkinje fibers
specialized fibers which relay impulses to the cells of the ventricles and cause them to contract, forcing blood out through the aorta
blood pressure
measurement of the amount of systolic and diastolic pressure exerted against the walls of arteries
systolic pressure
pressure occurring when the ventricles contract
diastolic pressure
pressure occurring when the ventricles are relaxed, between heartbeats
cardiomyopathy
term used to describe all diseases of the heart muscle
congenital heart defect
structural abnormalities caused by the failure of the heart to develop normally before birth
coronary heart disease
atherosclerosis of the coronary arteries that reduces the blood supply to the heart muscle
cholesterol
plaque on the interior walls of the arteries
ischemic heart disease
group of cardiac disabilities resulting from an insufficient supply of oxygenated blood to the heart
angina
condition of episodes of severe chest pain due to inadequate blood flow to the myocardium
nitroglycerin
vasodilator often prescribed to prevent or relieve the pain of angina; increases blood flow and oxygen supply to the heart
myocardial infarction
heart attack
infarction
sudden insufficiency of blood
occlusion
total blockage
congestive heart faliure
heart is unable to pump out all the blood that it receives, causes congestion
cardiomegaly
abnormal enlargement of the heart
heart murmur
abnormal sound heard when listening to the heart or neighboring large blood vessels
valvular prolapse
abnormal protrusion of a heart valve which results in the inability of the valve to close completely
valvular stenosis
condition in which there is narrowing, stiffening, thickening, or blockage of one or more of the valves of the heart
cardiac arrest
heart abruptly stops or even develops very abnormal arrhythmia that prevents it from pumping blood
arrhythmia
describes abnormality or loss of the normal rhythm of the heartbeat
atrial fibrillation
“a fib” occurs when the normal rhythmic contractions of the atria are replaced by rapid irregular twitching of the muscular heart wall
ventricular fibrillation
“v fib” rapid, irregular, and ineffective contractions of the ventricles
angiitis
inflammation of the blood or lymph vessels
angiostenosis
abnormal narrowing of the blood vessel
aneurysm
localized weak spot of balloon-like enlargement of the wall of an artery
arteriosclerosis
hardening of the arteries, any group of diseases characterized by thickening and hardening of arterial walls
varicose veins
abnormally swollen veins, valves in the veins malfunction and allow blood to pool in these veins, causing them to enlarge
thrombus
blood clot attached to the interior wall of a artery or a vein
coronary thrombosis
damage to the heart muscle caused by a thrombus blocking the coronary artery
deep vein thrombosis
condition of having a thrombus attached the the wall of a deep vein
embolism
sudden blockage of a blood vessel by an embolus
embolus
foreign object; blood clot, air, gas, fat, or tissue
hemochromatosis
iron overload disease; genetic disorder in which the intestines absorb too much iron
septicemia
blood poisoning; systemic condition caused by the spread of microorganisms and their toxins via the circulating blood
cholesterol
fatty substances which travels through the blood and is found in all parts of the body, not all bad
leukemia
cancer characterized by progressive increase in abnormal leukocytes found in the blood forming tissue
anemia
lower than normal number of erythrocytes in the blood
megaloblastic anemia
anemia in which the red blood cells are larger than normal
iron-deficiency anemia
iron is an essential component of hemoglobin. without sufficient iron to create hemoglobin, blood cannot carry oxygen effectively
sickle cell anemia
red blood cells assume an abnormal sickle shape
hypertension
elevation of blood pressure to a level that is likely to cause damage to the cardiovascular system
antihypertensive
medications such as ACE inhibitors and beta-blockers which lower BP
hypotension
lower than normal arterial blood pressure
thrombocytemia
abnormally small number of platelets circulating in the blood
